"BellSouth's Marriott code 256810 may still be active in Marriott's GDS system despite AT&T's acquisition in 2006. Codes from legacy companies often persist. No verification incidents documented. AT&T (which absorbed BellSouth) has a separate Marriott code (ATT) rated Low. Legacy codes from acquired companies are among the lowest-risk as they are rarely flagged for active monitoring."

"I have never been asked for ID in any hotel booking, even when using a rate code for personal travel."

"In North America I've been asked a single time in the 15 years I've been using Corp rates (for a few years I'd use them on multiple stays per week). My trick is to approach the counter in a friendly way, ask how they are doing, maybe ask an easy question about the hotel (where's the gym?) and connect with them (boy it's hot out there today!) They are happy to have met you, it is a pleasant experience, and you go on your merry way. I'm also Titanium for life and currently have Ambassador, but I've done this when Gold and Platinum. For that one time they asked I said I had actually just started and didn't have my business cards yet, but should have them for my next stay and they let it go. I was never asked by that hotel again (Courtyard Bellevue on an Accenture rate.) Doing a mobile check-in will also shorten the time spent. Just have your ID and card ready to speed things along."
